2. Introduction
The Fiber Optic A/B Switch with Loopback is an all optical, fiber optic, latching style A/B switch (maintains the
connection even when power is removed) that includes additional optical switching mechanisms to automatically
loopback the unselected port. For example, if position A is selected, the A port will be connected to the C port, while
any signals received on the B port will be looped back out port B. Likewise, if position B is selected, the B port will
be connected to the C port, while any signals received on the A port will be looped back out port A. This is
especially useful in failover applications, as this added functionality allows the “unused” circuit to be continuously
tested to insure that it is operating correctly and available for use if needed.
3. Installation
Place the switch in a location that is relatively free from vibration and mechanical disturbances.
Apply power to the switch by plugging the AC power supply module into the connector on the back of the switch,
and then plug the power supply module into a suitable source of AC power. Next, change the connection states of
the switch by rotating the front panel control knob between the A and B positions. This causes all of the internal
optical switch mechanisms to switch to an appropriate connection state prior to making any fiber optic cable
connections to the switch. As soon as the fiber optic cables are attached, the network connection between the C
port and the selected network port (A or B) will be immediately active.
Now that the switch connection state is configured for your application, connect the “shared” network connection to
the Port C fiber optic connectors. Connect the one fiber link (of the two to be switched) to Port A. Connect the
second fiber link to Port B
Take care to connect inputs and outputs consistently.
Note that the Fiber Optic A/B Switch with Loopback supports separate transmit and receive paths, so you must be
consistent when connecting the fiber pairs to the switch. The fiber optic connectors on the ST version of the switch
are marked “1” and “2” to help insure that the proper connections are made to each port. On the SC version of the
switch, the left connector position of the SC duplex connector for the C port is switched to either the left connector
position of either the A or B port duplex connector, and the right connector position of the SC duplex connector for
the C port is switched to either the right connector position of either the A or B port duplex connector. For example,
connect the receive in cable from your shared device to port C connector “1”, and connect the transmit out cables
from your network switches to port A connector “1” and port B connector “1”. In a similar fashion, connect the
transmit out cable from your shared device to port C connector “2”, and connect the receive in cables from your
network switches to port A connector “2” and port B connector “2”.
4. Operation
The Fiber Optic A/B Switch with Loopback incorporates full-duplex optical switch mechanismscontrolled by a front-
panel-mounted rotary A/B switch. It is used to share a fiber optic link between two fiber optic networks .
The switch utilizes a unique optical switching mechanism. When you turn the knob on the front of the switch to
select a port, circuitry activates the optical switch mechanisms causing them to redirect light beams from Port C
(the “common” port) to either Port A or Port B by rotating a gold-plated, spherical mirror. There’s no optical-to-
electrical conversion between your fiber optic links.
To operate the switch, simply turn the knob on the front panel of the switch to route the signals. Turning the knob to
position “A” will route signals from Port C to Port A, while simultaneously looping back signals on port B. And
selecting “B” routes the signals from Port C to Port B, while simultaneously looping back signals on port A.
And because the switch uses latching fiber optic switch mechanisms, if the switch loses power, it will continue to
pass signals between port C and the selected port, while also looping back the signals on the un-selected port.
5. Troubleshooting
If the Fiber Optic A/B Switch with Loopback fails to operate, check the following before calling for technical support.
1. Ensure that the power supply connected to a power source and to the switch.
2. Check the fiber optic connectors for proper connections to the correct ports of the switch.
3. Operate the switch knob to verify that it’s tightly secured to the switch shaft and does not spin loosely.
4. Verify the integrity of the fiber optic leads by replacing a suspect cable with a spare.

with the manufacturer’s instructions, may cause interference to radio communication. It has been tested and found to comply with the limits
for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference when the equipment is operated in a commercial environment. Operation of this equipment in
a residential area is likely to cause interference, in which case the user at his own expense will be required to take whatever measures may be
necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the
equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the Radio Interference
Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la classe A
prescrites dans le Règlement sur le brouillage radioélectrique publié par le Industrie Canada.
